has anyone fuzz ffmpeg,how to compile ffmpeg source code

[6231...@qq.com]

I download ffmpeg-0.11.1.tar.gz from https://ffmpeg.org/releases/  ,and then CC=../../afl-2.33b/afl-gcc CXX=../../afl-2.33b/afl-g++ ./configure --disable-shared; make

but when I do this afl-fuzz -i input/ -o output/ -m 1G -- ./ffmpeg -threads 1 -i @@ -threads 1 -f null /dev/null

I get this:

    Looks like the target binary is not instrumented! The fuzzer depends on

    compile-time instrumentation to isolate interesting test cases while

    mutating the input data. For more information, and for tips on how to

    instrument binaries, please see /usr/local/share/doc/afl/README.

    When source code is not available, you may be able to leverage QEMU

    mode support. Consult the README for tips on how to enable this.

    (It is also possible to use afl-fuzz as a traditional, "dumb" fuzzer.

    For that, you can use the -n option - but expect much worse results.)

One other way to quickly build a program you want to fuzz is to use
aflize Docker environment:
